Need help with algerbra homework

Question

here is the a similar problem to the one i am working on. i just need someone to show me the steps so i could do the one i have from school a little better:

C. Hicks owns a local ice cream parlor and yogurt stand. his single scoop cone seels for 89 cents and the "giant earthquake" of eight scoops is $6.07. the cost of the ice cream cone varies linearly with the number of scoop. find the equation.

(note: whoever is answering it please explain it while u show me.

Answer 1

Y= mx + b does work.  b is the Y intercept, which in this case is at 1 scoop, making it $.89.  b=.89.  m is the slope of the line which is rise over run.  rise is the difference in prices.  run is the difference in scoops.  Therefore we get $6.07-$.89/8-1, by the magic of simply running this through a calculator, we get the slope of $.74.  Thus m=.74.  X represents any number of scoops you want and must remain a variable in your equation.  Y is dependent on what you choose for x and therefore has to remain a variable in your equation.  Now plug in what you know

Y=mx + b

b=$.89 (see above)

Y=mx + $.89

m = $.74 (see above)

our final equation is

Y=$.74x + $.89

Good luck with the real problem.

Answer 2

well it could be y=mx+b but idk let me try to fit that problem in the equation. 6.07=8(0.89)x+ b i think you're suppose to solve it and find b. but im lost too lol
